Half-life (t1⁄2) is the amount of time required for the amount of something to fall to half its initial value. For a specific amount of time, we'd need a specific substance.
1/2 = 0.5 = 5 x 10^-1
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
The term is called half-life. It is the time it takes for half of the radioactive nuclei in a sample to decay.
Half life has unit. That is unit of time. So it has to be mentioned. Let us assume that half life is 1 year. Okay. Now to know about the mass remaining we have to get the ratio (1/2)^1620. Hence remaining will be 1/(2^1620) * mass at the beginning
Pu-239 has a half-life of 24,110 years.
No, not all elements have a half-life. Half-life is a property of radioactive elements that undergo decay over time. Non-radioactive elements do not have a half-life because they do not decay in the same way.
Half-life depends on the particular nuclide involved. You did not specify which nuclide. Please restate the question. Curie is a unit of radioactivity, expressed as 3.7x1010 disintegrations per second. It is not a radionuclide. If you meant curium, you still need to specify which isotope, because curium has several. The longest lived isotope of curium is 96247Cm, with a half-life of 1.56x107 years.

No, half-life refers to the time it takes for half of the atoms in a radioactive substance to decay, not the activity itself. Activity is a measure of the number of decays per unit time, which decreases as the amount of the radioactive material diminishes. Thus, while half-life provides a timeframe for decay, it does not directly describe the activity level.
It is 1.5 times the unit price.
A Geiger counter detects radiation by counting the number of decay events that occur. Radioactive material with a long half-life decays more slowly, resulting in fewer decay events per unit time compared to material with a short half-life. Therefore, the Geiger counter will record a lower counting rate for radioactive material with a long half-life.
No. Half Life: Opposing Force does not require neither Half Life nor Half Life: Blue Shift.
The half-life of a quantity whose value decreases with time is the interval required for the quantity to decay to half of its initial value. The concept originated in describing how long it takes atoms to undergo radioactive decay but also applies in a wide variety of other situations.Half-lives are very often used to describe quantities undergoing exponential decay-for example radioactive decay-where the half-life is constant over the whole life of the decay, and is a characteristic unit (a natural unit of scale) for the exponential decay equation. However, a half-life can also be defined for non-exponential decay processes, although in these cases the half-life varies throughout the decay process. The converse for exponential growth is the doubling time.
In the family tree, the unit of life is genes.
Cells are the fundamental unit of life.

Yes, 0.5 grams is equal to half a gram. The term "half" indicates that it is 50% of a whole unit, and since 1 gram is the whole unit, 0.5 grams represents half of that.
